MATRIX FOR TYPOGRAPHICAL MACHINES.

Application filed August 8 1924. Serial No. 730,897.

The present invention relates toimprovements in matrices of the kind adapted for use in typographical machines and more particularly to those of the kind adapted for use in machines of the linotype class.

The primary object of the invention is to provide matrices which have the same general formas those of the usual or standard kind, which are capable of being used with the usual or standard matrices and handled by the same mechanisms of the machine, but embodying means by which they may be readily and efficientlydistinguished and separated by the distributing means of the machineso that these matrices may be properly distributed or returned to their approprlate magazines with the same speed and facility as the usual or standard matrices are returned to their magazines. To these and other ends the invention consists in certain improvements as will be hereinafter set forth, the features of novelty being pointed out particularly in the claims at the endof the specification.

In the accompanying drawing Figure 1 is a perspective viewof a character bearing matrix embodying a straight groove in one of the fiat side walls thereof. Figure 2 is perspective view of a -cha'1' acter-bearing matrix embodying a curved or 'arcuate groove in one of the side walls thereof.

Figure 3 is a diagrammatic view of a por tion of the I matrix distributing mechanism of a typographical machine in which the improved matrices are adapted to be used, this figure showing means for distinguishing and separating those matrices having a straight groove therein from those having a curved or arcuate groove, a matrix having a straight groove being" shown passing the distinguishing and separating means; and

' Figure 4 is a View similar to Figure 3 but showing a matrix having a curved groove in the course of its passage through the distinguishing and separating means;

Similar parts are designated by the same reference characters in the different views. The present inventionis applicable genorally to typographical machines of the kinds using circulating character-bearing matrices which are'stored in a magazine or magazines and are released and delivered therefrom for assembly into a line for the Jar )ose of castin a ty e bar or slugthere l b from, after which the matrices are returned and distributed to the magazine or mega:

ard matrices and enables them to be sepa rated therefron'i by matrix distinguishing or separating means in the machine; Matrices of the preferred construction are illustrated in the accompanying drawing and will be hereinafter described in detail. It is to be understood, however, that the invention is not restricted to the precise construction shown, as equivalent constructions are contemplated, and such will be included within the scope of the claims. 7

In the present instance, M (Fig. 2) illustrates substantially one of the matrices of improved form, it beinglunderstood'tha-t all of the matrices comprising a font will have the same general outline as the usual or standard matrices as commonly used in type graphical machines. In the present instance, where the matrices are adapted for use in machines of the linotype class, each matrix has one or more characters m in its forward or character-bearing edge, the top or upper end ofthe matrix is provided with combi-' nation teeth m to co-operate with the usual ribbed distributor bar, and the corners of the matrix are formed with the usual lugs or cars m which guide and support the matrices'in the machine in the usual Well known manner, I v

The in'iproved matrix M differsfrom the usual orstandard matrix in the respect that it has a curved or arcuate groove or recess ,The groove m preferably extends from the upper to thelower end of the matrix and it is'preferably of curved form of substantially uniform width and depth. Furthermore, the groove is curved in the direction of the plane of the side of the matrix in which it is formed and preferably the curvature of the groove is on true are of a circle. The groove M will be provided in all matrices belonging to a given iiont, and the groove will be similarly formed and located in all of such matrices.

The matrix M (Fig. 1) also differs from the usual or standard matrix in that it has a vertical or straight groove or recess m formed in a side of its body. This groove or recess serves to distinguish matrices bearing the same from those of other fonts in the machine and it provides means by which such matrices are separated from those of other fonts. The groove on extends from the upper to the lower end of the matrix vertically and is substantially of uniform width and depth.

The improved matrices provided by the present invention are adapted for use in a typographical machine which is provided with suitable means for distinguishing and separating the improved matrices according to the presence of the curved groove m or the straight groove m For example, the improved matrices as herein shown are adapted for use in a typographical machine o:t' the linotype class embodying matrix distinguishing and separating means of the kind illustrated and described in my co-pending application Serial No. 730,898 filed August 8, 1924;. Reference is made to that application for a full and complete illustration and description of such matrix distinguishing and separating means. For the present purposes, it is believed to be sullicient to refer to Figures 3 and 4 of the present application which illustrate generally the matrix distinguishing and separating means set forth in my co-pending application. In these figures, 3 represents a portion of the separating means which is interposed between the distributor bar and the upper ends of the superposed magazines in which the improved matrices are stored, the upper end of the channel entrance i being located immediately below the distributor bar so that it will receive the matrices dropping therefrom while they are in the course of distribution, as is well understood, and the lower end of the channel entrance is formed with upper and lower branches r and r to conduct the distributed and separated matrices into the upper and lower magazines respectively. The channel entrance is constructed in the usual manner, of a number of suitably spaced partition plates providing passages which respectively receive the matrices of corresponding character which are released at the appropriate points in the length of the distributor bar, and serve to conduct the separated matrices respectively to the upper and lower magazines. The matrix distinguishing and separating means, which is shown as embodied within the channel entrance, comprises a series of rails 5 which are secured to and project laterally into the respective matrix passages. Each rail is preferably curved on a true are of a circle of appropriate radius, and it leads from a throat i in the upper portion of the matrix passage. in a circular direction downwardly and forwardly to ard the upper magazine. The upper end of this rail being arranged in the path of the falling matrices itwill direct those matrices having the curved groove out of the passage and will lead such matrix while supported thereon, through the passage et into the upper magazine, the upper end of which is designated A. The matrix M which is distributed from the distributor bar in identically the same manner as a matrix M and through the channel entrance or throat forms a connection with the rail 5 at its upper end 5, and by reason of the fact, that it has a straight groove as distinguished from the curved groove of the matriX M, this matrix M passes through the opening 5" of the rail 5 and is delivered straight down through the portion 45 of the throat into the lower section of the channel entrance and is lead therefrom to the lowermost magazine illustrated more l'ully in the corresponding application tiled herewith.

The present invention enables matrices of the usual form to be employed. I have provided in the side walls of the matrices either a straight groove or a. curved groove to effect separation of the sorts as they are delivered into the throat l from the usual distributor bar and channel entrance. The separating means which is operative upon the matrices as they are delivered to it comprises simply curved rails which extend into the proper positions in the paths of the dcscending matrices where they are directed to engage these rails. All matrices they are delivered engage the upper ends of the respective separating rails, and if provided with a straight groove, such matrices will pass directly through the opening 5 of the rail to the lower matrix channel and to the lower magazine. If, however. a matrix is provided with a curved groove in its side wall and such matrix engages the separating rail, it will be diverted from the path of the vertically falling matrices into the uppenmatrix channel and to the upper magazine.

I claim as my invention 1. A matrix for use in typographical machines, having a single groove extending continuously in a side wall and from top to bottom thereof, the shape of said groove distinguishing the matrix as to font and accordingly determining its path of travel.

2. A matrix for use in typographical machines, having a single groove extending longitudinally therethrough in a side wall and from top to bottom thereof, said groove having a shape which distinguishes the matrix as to font and accordingly directs its path of travel.

3. A matrix for use in typographical machines, having a groove in a side wall thereof which is curved from top to bottom of the body of the matrix.

4. A font of matrices for use in a linecasting machine, each matrix belonging to such font being provided on a side face thereof with a throughout the length of the matrix and is curved in the plane thereof.

5. A plurality of fonts of materices for use in a typographical machine, the matrices of one font each having a single straight groove which extends groove in a side of the body thereof which extends throughout the length ofthe matrix, and the matrices of another font having a groove in a side thereof which extends throughout the length of the matrix and is curved in the plane thereof.

6. Fonts of matrices for use in a typographical machine, the matrices of one font each having a distinguishing groove in a flat side thereof which extends throughout the length of the matrix and is curved in the plane thereof, and the matrices of another font each having a straight groove in a flat side thereof which extends throughout the length of the matrix, the openings of the distinguishing grooves in the ends of the matrices of the different fonts being in the same relative positions on the matrices.

In testimony whereof I have hereunto set my hand.
